Question

There are times when I want to convert user input into its literal value in a regular expression. I.e. if the user enters C:\Win\Bin\File.txt the regular expression would be something like C:\\Win\\Bin\File.txt since certain character combinations have to be escaped. Does anyone know of either a tried and true piece of code that does this, or some other technique that does this automatically?

Answer 1

Have you tried Regex.Escape()?

E.g.

var userInputRegex = new Regex(Regex.Escape(userInput));
